Do solar inverters need AFCI protection?
These rules mandate that all solar inverters operating at any DC voltage higher than 120 V have to include AFCI protection to prevent fires caused by arc faults. Solar inverters without AFCIs were still allowed until the end of 2024, but from 2025 onwards, compliance is mandatory for certification and safety inspections.
Do solar PV systems need AFCI protection?
In the U.S., the National Electric Code (NEC) has required AFCI protection for solar PV systems with DC circuits over 80 V since 2011 (NEC 2023 690.11). This regulation mandates that all systems installed in or on a building must include measures to detect and interrupt arc faults.
What is DC AFCI?
AFCI (Arc Fault Circuit Interrupter) is a specialized safety device engineered for photovoltaic (PV) systems. Its primary function is to detect and interrupt dangerous electrical arcs within the DC circuits of a solar array.
Do PV inverters have arc fault detection?
Fires at traditional PV stations cannot be directly put out with water because of the high DC voltage, so installing PV inverters that are equipped with the arc fault detection function is a must. What is an AFCI circuit breaker and how does it work?
